Application filed September 25, 1924. Serial No. 739,809.

To all whom it may concern.-

. Be it known that I, JAMEs A. JENSEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Faucets, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates generally to faucets, more specifically speaking to drain or service faucets, adapted for use in connection with motor tank vehicles of the kind ordinarily employed in transporting gasoline, lubricating oils, or other liquid commodities.

My invention is directed to improvements in faucets of the above mentioned character which are calculated to promote quick valvular action; to reduce to a minimum, head resistance to flow through such faucets; and in general, to secure the advantages of structural simplicity, both from the standpoint of economy in manufacture, and reliability against derangement in use.

With reference to the drawings, Fig. I a plan view of a drain faucet conveniently I embodying my invention, a portion being shown broken away and in section to expose certain important structural details.

Fig. II is a sectional elevation of the same showing the valve open.

Fig. III is a view similar to the preceding but with the valve closed, and

Fig. IV is a cross section taken as indicated by the arrows IV-IV in Fig. III.

-As herein represented the faucet of my invention comprises a main casing member or section 1 which constitutes the valve chamber, and an auxiliary section 2 in the form of an elbow which serves as an outlet or spout, the two sections being screwed together as at 3. This arrangement facilitates introduction initially, of the movable valve partsyas well as removal .of the same subsequently, to enable replacements to be made when necessary. The inlet end of the main casing member 1 is internally screw threaded as at 4, after common practice, for convenience in application to a drain pipe such as shown at 5. The spout section 2 is provided with an integral hanger lug 6 that serves as a support from which a bucket or can may be suspended for filling. A nipple 7 removably screwed into the discharge end of the spout section 2, permits a hose to be attached as is desirable-in connection with tank vehicles to permit draining in bulk, as for example when gasoline is to be delivered in tank quantities at filling stations. 4

The movable closure or valve member of the faucet comprehensively designated 8, comprises a hollow piston 9 that is open at the back and formed with an integral rearwardly extending coaxial stem 10, as well as with a forwardly-extendingcentral stud projection 11. y is supplemented with a removable facing 13, of rubber or compressible composition, which is medially apertured to fit about the stud projection 11 and held in place by a jamb nut 1ft with aid of an associated washer 15. The facing 13 is well rounded peripheerally as shown so as to be capable of engaging a cooperating annular seat 16 inthe elbow or spout section 2 with a snug, fluidtight fit. An abutment head 17 (Fig. IV)

supported coaxially within the valve chamber 1 by a number of integral radial fins 18, is centrally pierced to slidably receive the stem 10 of the valve piston 9, and to accurately guide the latter in its movement toward and away from the'seat, 16. In order to assist such guidance and to offset the possibilityof binding or sticking, the radial fins 18 are extended longitudinally of the casing At the front, the piston 9 as shown at 19 to afford the piston 9 fur-' ther support in its endwise travel. The valve 8 is normally held closed as shown in Fig. III by a spring 20 in compression between the piston 9 and the abutment-head 17. This spring 20 is made volute in form from fiat metal of such width that the same, when fully compressed, as in Fig. II, is wholly accommodated within the closed cavity jointly formed by the abutment head 17 and. the hollow of the piston 9 when the valve 8 is in full open position. By this arrangement, as will be readily appreciated, the valve parts are very closely compacted and the spring 20 entirely eliminated as a source of flow resistance-incidental to drainage through the valve. In this connection it is to be particularly noted that the leading face of the abutment head 17 is divergently sloped to function as a baflle in diverting flow through the faucet uniformly outward for ready and easy passage about the valve 8, the end of the valve stem 10 and the radial fins 18 being also tapered as shown with the result that the head resistance of the whole organization within the valve chamber 1 is reduced to the very minimum.

As a means for operating the faucet, I

employ a handle 21 which is afiixed to the end of a shaft 22 that extends laterally through a stuifing box 23 into the section 2 of the casing to afford attachment for a tappet 24. This tappet 24 engages the end of the stud extension 11 at the posterior side of the valve piston 9. Thus, by depressing the handle 21, the tappet'24; is swung clockwise and the valve 8 shifted axially inward against the pressure of the spring 20, and in a direction opposite to the flow through the faucet, the abutment head 17 functioning as a stop to limit such movement and thereby determining the full open position of the valve.

Having thus described my invention, I claim 1. In a faucet-of the character described, the combination of a casing providing a concentric abutment head having the leading face divergently sloped and a valve seat; a hollow closure member afforded guidance in the abutment head while movable toward and away from the valve seat; a spring infiuential upon the closure member to resist valve opening; said abutment head operating with the closure member to form 'a confined cavity for wholly accommodating the spring when compressed.

2. In a faucet of the character described, the combination of a casing providing a valve seat; a hollow closure member movable toward and away from the valve seat; a volute spring influential upon the closure member to resist valve opening; and a fixed abutment in said casing having the leading face thereof divergently sloped, said abutment affording guidance for the closure 2 member while co-operating therewith to form a confined cavity for wholly accommodating the spring when compressed.

3. In a faucet of the character described, the combination of a casingproviding a valve seat; a hollow closure member movable coaxially within the casing toward and away from thevalve seat; and a fixed abutment head centrally of the casing affording guidance for the closure member, said head having its leading face divergently sloped to divert the fiow uniformly outwardly and {)acilitate its passage'about said closure mem- 4. In a faucet of the character described,

the combination of a casing providing a valve seat; a closure member movable toward and away from the valve seat; a spring influential upon the closure member to resist valve opening; and a fixed abutment head within the casing cooperating with the closure member to form a closed cavity for wholly accommodating the spring when compressed, said head having its leading face divergently sloped to divert the flow uniformly outwardly and facilitate its passage about said closure member. I 5. In a faucet of the character described, the combination of a casing providing a valve seat; a closure member having a rearward projecting stemimovable toward and away from the valve seat; and a fixed abutment head centrally pierced to slidingly receive the stem of the closure member, said head being supported coaxially within the casing by a number of radial ribs, and said ribs extended longitudinally of the casing to assist in guiding said closure member.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this'22nd day of September 1924:.

JAMES A. JENSEN.
